well Catholicism is monotheistic, but they don't believe that your soul belongs to God when you're born.. don't you become a Christian when you get baptised? And that also is supposed to clear one of the original sin.

Well, from some of the orthodox Jewish people I used to chill with first year university, alot of them didn't believe catholicism was monotheistic because of the "father, son, holy Ghost"

I have also taken christianity, and I have a few Bibles, I just haven't had time to study it properly.

But yes, your baptism does clear your original sin as far as I remember...

Muslims don't believe in original sin. Adam and Eve were equally responsible for what happened, and giving birth is a blessing because mothers are 3 times more entitled to respect and love from their children than the fathers.

I hear ya on both points. Catholics themselves say they are monotheistic.. the holy trinity certainly takes something away from the 1 true god that jews and muslims believe.. at least I think so.

ditto for jews on the original sin. Jews believe that humans are born free of sin, and if man sins it is because he is not a perfect being, unlike christianity which teaches that he is inherently evil.
